* make functions to print assembly out
|
|
* how can you add 68030 support? Should it be all one module that checks maybe during decode if the instruction is supported? Should it 'inherit' from the MC68010 object
|
|
* make tests for each instruction
|
|
|
|
* unimplemented: ADDX, BKPT, CHK, EXG, ILLEGAL, MOVEfromCCR, MOVEP, RTR, RTD, SUBX
|
|
* undecoded: ADDX, SUBX, ABCD, SBCD
|
|
* modify execution for >=MC68020: DIVSL, DIVUL, EXTB, LINK, MOVEM, MULSL, MULUL, RTM, TRAPcc, UNPK
|
|
* implement the full extension word for MC68020+
|
|
|
|
* >=MC68020 instructions: BFCHG, BFCLR, BFEXTS, BFEXTU, BFFFO, BFINS, BFSET, BFTST, CALLM, CAS, CAS2, CHK2, CMP2, PACK
|
|
* Coprocessor instructions: cpBcc, cpDBcc, cpGEN, cpScc, cpTRAPcc
|
|
|
|
|
|
* should you simulate clock ticks, and only step devices when they next request it
|
|
* how can you have multple CPUs
|
|
* should you simulate bus arbitration?
|
|
|
|
|
|
* check all instructions in the docs
